This invention 'relates broadly to apparatus for cleansing metal sheets, and more specifically to a machine for cleansing such sheets immediately following the pickling operation. a

\ The primer object of the invention is to provide a mac ine whereby metal sheets may be more or less thoroughly cleansed, rinsed and dried following their removal either from the'pickling tank or from a rinsing I tank to which they are delivered following the pickling 0 eration. o

A furthero je'ct is to provide a mechanism'by means of which the surfaces of pick} led sheets are subjected to the sprayin action of numerous high pressure jets 0 hot water whereby said surfaces are effectually cleansed.

- In describing the invention in detail, reference is herem had tothe drawings, in which- Figure 1 is, a side elevation of the inven-' tion' Figure 2 is a top plan view of the same; Figure 3 is an enlarged section'qon line 3-3, Fig. 2;

Figure 4 is an enlarged under slde elevation of the upper spray member;

Figu of the lower spray member, taken centrally of one of the water-chambers; and

Figure 6 is an enlarged fragmentary section of a spray member, showing the form of the spray ports or jets.

accompanying each of two oppositely disposed frame mem bers which, as herein shown, rest upon transverse I beams 2 supported upon a suitable are loosely fitted sleeve portions 5 formed on oppositely disposed top frame members 6 which overhang the lower frame members 1.

Journaled in bea rings 7 carried by the lower frame members are the lower rolls of a plurality of sets of rolls which occupy spaced relation and which are herem desigo nated 8, 9

chambers 15 which are suitabl re 5 is an enlarged transverse'secti'on Referring to said drawings, 1 designates and 10; and journaled in bearings ll carried by the upper frame members mi the upper rolls of said sets, said upper rollsbeing normally disposed in overlying seated relation to the lower rolls and serving to support said upper frame members.

The set of rolls 8, located at the entrance end of the machine, and the set of rolls 9,- located a suitable distance in advance of said rolls 8, are designed as conveyor rolls whereby the sheets to be cleansed are advanced, and interposed between said sets 8 and 9 are upper and lower fluid-spraymember's' 12 and 13 which overlie and underlie, respectively, the path of travel of metal sheets which are advanced by saidconveyor rolls.- Each of I said spray members is preferably made in the form of a single metal casting, the u per member comprising a flat plate-like ody 12 which has its opposite ends attached, as, by means of bolts 14, tothe under sides of" the top frames 6. Located upon theupper, face-of said body 12 and formed integrally A with the latter is a plurality of transversely disposed hollow ribs constituting water end, as by plugs 16, and whic have branch water supply pipes 17 connected to their opposite ends, as shown, said branch pipes leading from a'main supply pipe 18. The pipe 18 has sufficient flexibility in its cou- B0 plings at the ends of the vertical part thereof to allow sufiicient yielding of the upper frame members 6, but the-specific manner by which "the fluid is supplied forms no part of the invention; and in case greater flexibility is desired, the pipe may be made of woven metallic or other hose.

The lower member'13 likewise comprises a plate-like body 13 which has its ends mounted in place, as by means of bolts 19, to the top faces of the lower frame members 1. Formed upon the under face of said body 13 are, transverse hollow ribs constituting water chambers 20, similar in form to the chambers 15 hereinbefore referred to, which have communicating therewith at one end .branch water supply pipes 21 leading from the supply pipe 18.

Each of the chambers 15 and20 is provided with means whereby water may be diclosed at one 75 vrected therefrom into contact with the adja- Instead of such row of holes 22, the first. of-

each series of water chambers may have therein a series of slots 23, staggered or otherwise, through which relatively large streams of water may be directed upon the sheets, such streams serving initially to flood the sheet surfaces, and the water delivered in sprays through the jets at high pressure acting to produce a scrubbing efl ect upon the previously flooded surfaces of the sheets.

From the rolls 9, the sheets are passed between guide members 24 to the rolls 10 which,

preferably, are designed to free the surfaces of such sheets from moisture which adheres thereto following the cleansing and rinsing effected as aforesaid. Said rolls 10 may be made of metal, rubber or-any other appropriate material, but preferably have a surface covering 10- of a soft, pliable fabric, as flannel, whereby the moisture carried by the sheets is absorbed or squeezed oif. From said rolls 10 the sheets pass to endless conveyor belts 25 whereby they are advanced to a piling point.

The various sets of rolls of the mechanism may be driven through any suitable gearing,

that herein shown comprising a drive chain 26, connecting sprocket wheels 27 and 28 carried by a motor shaft 29 and an end of the lower of rolls 9, respectively. The rolls 8 and 10'are, inturn, driven from the rolls 9 by sprocket chains 30 and 31., respectively.

The upper frame members 6, which have the thereby carried upper rolls of the various sets of rolls normally resting upon the lower rolls of said sets, are rendered readily yieldable in a vertical. direction by the provision of coil springs 32 in encircling relation to the projecting upper ends of the posts, said springs having their lower ends seated upon said upper frame members and their upperends resting against-collars 33 which are re-' movably mounted on said posts. Manifestly, said springs permit such vertical movements of the upper frame members and the thereby.

supported rolls as may be required to permit unobstructed passage of sheets through the rolls. A further object of the sectional construction described is to permit of ready access for cleaning the machine, the upper frame sections, top-rollsand upper spray member being removable as a unit when the branch water pipes 17 have been disconnected.

In practice, metal sheets, taken directly from an adjacent, or conveniently located,-

pickling tank 3 are entered between the rolls 8, whence they are advanced between the oppositely facing spray members 12 and 13 to the rolls 9. Such sheets are first flooded with hot water directed against their opposite surfaces throu h the slots 23 and are subsequently impinge by numerous sprays of hot water forcibly irected through the jets 22. The water so applied acts to scrub the surfaces of the sheets and to effect athorough cleansing and rinsing thereof. The drying rolls 10 serve to remove any water or moisture borne by the sheets following passage of the latter through the conveyor rolls 9.

What is claimed is 1. A sheet cleansing machine comprising a sectional frame wherein an upper section overlies and is, vertically movable relative to a lower section, a plurality of sets of conveyor rolls, the. lower rolls'of said sets bein journaled in the lower frame section and t e top rolls on the upper section, and a sheet spraying device disposed between adjacent sets of said rolls on each side of the path of sheet travel from one set. to the other, the upper and lower spraying devices being carried by said upper and lower frame sections, respectively, each of said devices including in an integral structure a member forming a sheet, guide and having a pluralityof transversely disposed .water chambers having therein discharge openiiigs facing the path of sheet constituting water chambers and being provided with jet openings for directing water from said chambers toward said path'of sheet travel.
